Contract Method Validation Jobs in California (NOW HIRING)

Xona is the navigational intelligence company bringing real-time, centimeter-level certainty to any device, anywhere on Earth.

With Pulsar – the world’s most advanced PNT satellite infrastructure in Low Earth Orbit – Xona will offer a future-proof, backwards-compatible global positioning system optimized for absolute precision, superior power, and robust protection.

Xona's Manufacturing team is responsible for the assembly, integration, and test of flight hardware, including the printed circuit board assemblies (PCBAs) that go into every satellite subsystem. We're looking for a Senior Manufacturing Engineer to own how those boards get validated once they land in our factory — from receiving through functional release to build.

As the technical owner of PCBA validation and test, you will define the production/process validation testing (PVT) strategy for incoming boards, drive it into digital work instructions, and close the loop with our contract manufacturers when hardware doesn't meet spec. You've worked inside a PCBA production environment before and know the difference between inspecting boards and actually controlling the process that produces them. You'll bring that experience to a small, fast-moving team building flight hardware for the first time at rate.

What You’ll Do:

• Define and own the acceptance test strategy for PCBAs - receiving inspection, quality checks, conformal coating inspection, and functional or environmental screening as warranted; you’ll drive continuous improvement in cycle time

• Translate schematics, assembly drawings, and IPC-A-610 / J-STD-001 workmanship criteria into inspection and test procedures embedded directly in digital work instructions and travelers

• Specify, build, and qualify test fixtures, functional test stations, and the instrumentation behind them (power supplies, DMMs, oscilloscopes, signal generators, data acquisition systems)

• Own nonconformance management for incoming boards — containment, root cause analysis (8D/5-Why/Fishbone), and MRB disposition

• Work with the Quality Assurance and Supply Chain teams to conduct PCB contract manufacturer audits and own SCAR workflows, driving supplier corrective action to closure

• Build measurement and test confidence through gage/test method validation; Gage R&R & Cpk

• Analyze yield, defect, and escape trends from incoming PCBA data to drive both supplier-side and internal process improvement

• Partner with electrical design and systems engineering to feed manufacturing and test data back into DFM for future board revisions

• Mentor engineers and technicians on PCBA inspection and test practices as the team and factory scale

What You Bring:

• B.S. in Electrical Engineering, Manufacturing Engineering, Mechanical Engineering, Industrial Engineering, or equivalent practical experience

• 5+ years in manufacturing or test engineering in a PCBA/electronics production environment (3+ with an advanced degree)

• Direct experience standing up or owning production/process validation testing (PVT) for electronic assemblies

• Working knowledge of IPC-A-610 and J-STD-001 workmanship and acceptance standards

• Experience with PCBA test methods: ICT, flying probe, functional test and the fixtures and equipment behind them

• Ability to read and interpret schematics, assembly prints, and BOMs, with working knowledge of GD&T

• Experience with nonconformance management and root cause analysis

• Hands-on in a PCBA production environment, working directly with technicians and CM partners on process improvements

Preferred Qualifications:

• 7+ years in manufacturing or test engineering in a PCBA/electronics production environment

• Experience in aerospace, space, defense, or other high-reliability electronics

manufacturing (IPC Class 3, J-STD-001 Space Addendum)

• PCB or electronics contract manufacturer audit experience

• Experience with MES/ERP systems and configuration-controlled manufacturing records

• Programming experience (Python or similar) for test automation or data analysis

• Experience scaling a validation process from NPI/first article through repeatable production rate
